Journal ArticleDOI
The evolution of parasitism in plants.
TL;DR: This review focuses on the Orobanchaceae, which are unique among the parasitic plants in that extant member species include the full range of host dependence from facultative to obligate parasites.
Journal ArticleDOI
MicroRNAs from the parasitic plant Cuscuta campestris target host messenger RNAs.

TL;DR: Data show that Cuscuta campestris haustoria accumulate high levels of many novel microRNAs (miRNAs) while parasitizing Arabidopsis thaliana, and suggest that they may act as virulence factors during parasitism.
Journal ArticleDOI
Convergent evolution of strigolactone perception enabled host detection in parasitic plants
Caitlin E. Conn,Rohan Bythell-Douglas,Drexel A. Neumann,Satoko Yoshida,Bryan Whittington,James H. Westwood,Ken Shirasu,Charles S. Bond,Kelly A. Dyer,David C. Nelson +9 more
TL;DR: Functional analyses of parasitic plant strigolactone receptors in transgenic Arabidopsis suggested that convergent evolution has occurred to allow the parasitic plants to detect their hosts, and it was observed that KAI2, but not D14, is present at higher copy numbers in parasitic species than in nonparasitic relatives.
Journal ArticleDOI
Genomic-scale exchange of mRNA between a parasitic plant and its hosts
TL;DR: It is demonstrated that parasitic plants can exchange large proportions of their transcriptomes with hosts, providing potential mechanisms for RNA-based interactions between species and horizontal gene transfer.
Journal ArticleDOI
Functional Analysis of a Predicted Flavonol Synthase Gene Family in Arabidopsis
Daniel K. Owens,Anne B. Alerding,Kevin C. Crosby,Aloka B. Bandara,James H. Westwood,Brenda S.J. Winkel +5 more
TL;DR: This study showed that the other expressed AtFLS sequences have tissue- and cell type-specific promoter activities that overlap with those of At FLAVONOL SYNTHASE1 and encode proteins that interact with other flavonoid enzymes in yeast two-hybrid assays, suggesting that these “pseudogenes” have alternative, noncatalytic functions that have not yet been uncovered.
